SAFETY-PIN.

Specification of Letters Patent.

Patented Sept. 26, 1911.

To all whom it may concern:

Be it known that we, LoUIs FALSTREM, of Gravenhurst, in the district ofMuskoka, Province of Ontario, in the Dominion of Canada, and CHARLnsBURKLAND, resident of J arlsburg, in the district of Parry Sound, in theProvince of Ontario, in the Dominion of Canada, both subjects of theKing of Great Britain, have invented certain new and useful Improvementsin Safety-Pins, of which the following is a specification.

The invention relates to improvements in safety pins, as described inthe following specification and illustrated in the accompanying drawingsthat form part of the same.

The object of the invention is to obviate the difficulties andannoyances due to the accidental unfastening of the pin, and it consistsessentially in the novel construction of a length of wire, whereby thepoint of the pin is retained securely in the guard loop by a springlooped member extending in wardly from the back of the pin and coactingwith the two members of the guard loop, closing the opening to saidguard loop.

In the drawings, Figure 1 is a perspective View of the pin constructedin accordance with this invention. Fig. 2 is a sectional view of the pinshowing the exact relative arrangement of the guard, spring loops andpin.

Like numerals of reference indicate corresponding parts in each figure.

Referring to the drawings, 1 is the pointed pin member having the springcoils 2 formed at one end thereof. I

3 is the back of the pin formed by an extension from the spring loop 2extending outwardly and bent to form a crook shaped hook 4. The wire atthe terminal end of the crook shaped member 4 is bent to form the guardloop 5 adapted to receive the pointed end of the pin. The wire is thenbent to conform to the shape of the crook shaped portion 4 and the upperside of the pin and is curled around the back portion 3, the loop 6formed by said curled portion being arranged directly opposite theinwardly projecting angular portions 7 of the guard loop. *rom the loop6 the wire is bent inwardly toward the guard loop and bowed to form thes ring loop 8, the terminal end of the wire eing wrapped around the back3 against the loop 6. The loop 8 is of substantial elliptical shape andthe outer rounded sides of the outer end touches the inner sides of theoutward portions of the guard loop, the extreme point of the ellipticalshaped loop 8 extending forward partially into said guard loop andclosing the opening to said loop.

In the use of this article the point of the pin enters the guard loop bypressing it against the side of the spring loop 8 and the said springloop 8 springs sidewise sufficiently to allow the pin to drop into thesaid loop 4, the spring guard 8 returnin immediately and closing thepassage to said loop, thus preventing the pin from being accidentallyopened. It will thus be seen that the said pin is held securely but whenit is desired to open the same the spring loop will spring to eitherside to allow the pin to escape from the loop 5 on sufiicient pressurebeing brought to bear on it. The pin may be closed very easily and alsoopened very easily but when closed prevents the pin point from beingaccidentally withdrawn.

What we claim as our invention is In a safety pin formed from a singlelength of wire with a U-sectioned point guard at one end, an integralresilient loop member disposed in a plane substantially at right anglesto the pin and extending from opposite said point guard and bridgingacross and contacting with the sides of said guard at the mouth thereof.

Signed at Parry Sound, Ontario, Canada, this 21st day of October 1909.
